SpaGuard® Rapid-Dissolve pH Decreaser Tabs (1.25 lb)

Q: How fast do the tablets dissolve?

A: They dissolve completely within minutes, releasing active ingredients quickly for fast pH correction.

Q: Can I use these with any sanitizer system?

A: Yes — they’re compatible with chlorine, bromine, salt, ozone and mineral systems.

Q: How do they compare to liquid acid products?

A: They work similarly to liquid pH reducers but are safer, easier to dose, and require no mixing.

Q: Will these tablets affect total alkalinity?

A: When used as directed, they mainly target pH and minimally impact total alkalinity.

Q: How often should I use them?

A: Only as needed based on test results — regular testing will indicate when adjustments are necessary.

Test spa water to determine current pH level. Ideal pH range: 7.2 – 7.6.

With the circulation system running, add 2 tabs per 250 gallons of water if pH is above 7.8.

Allow tabs to dissolve and circulate for at least 15 minutes.

Retest pH after 4 hours and repeat if necessary.

Always store tightly sealed in a cool, dry place out of direct sunlight.
